This is a first for me, as I cannot recall the last time there was an optional cumulative update.
Since issues with search and CPU usage spiking were reported very early on, I decided to just ignore the Download and install link on the Windows Update pane for this specific update.
As of today (not sure exactly what time) the message regarding it being available and the above noted link disappeared from the Windows Update pane. After checking update history it's clear that it did not apply on its own.
So that's a new data point for me. I had wondered whether, after ignoring it for a sufficiently long time, it might automatically download and install even though it was designated as optional. It didn't do that.
